Perivascular adipose tissue in

cardiovascular diseases

To the Editor,

We congratulate Grigoras et al. (1) on their comprehensive

and perceptive review titled “Perivascular adipose tissue in

cardiovascular diseases-an update”. However, some additional

comments may be of interest.

Grigoras et al. (1) report that the perivascular adipose tissue

(PVAT) differs in properties depending on its anatomical location.

Other authors have also reported similar findings (2). These

prop-erties, together with the anatomical structural variations, may

eventually facilitate the use of a specific treatment for a specific

blood vessel, in addition to the usual general measures. In this

context, we also need to consider that blood vessels, at different

locations, may have different receptor distributions (3).

An abnormal PVAT is probably associated with abnormal

peri-organ and intra-peri-organ fat at other sites, and this may indirectly

increase the risk of vascular events (4-6). Grigoras et al. (1) also

mention the potential role of various drugs on PVAT. This will be

an area of considerable interest for further research (1, 6).

Grigoras et al. (1) discuss a carotid model in the context of

PVAT. Indeed, other authors have reported links between the

PVAT and internal carotid arteries (ICA) stenosis (7).

Further-more, the pericarotid fat density has been associated with an

increased risk of stroke and transient ischemic attack in patients

with unilateral ICA stenosis ≥50%–99% (8).

The review by Grigoras et al. (1) made a considerable

contri-bution to the field discussed above.

Declaration of Interest: N.K. has given presentations, attended con-ferences, and participated in trials sponsored by Amgen, Astra Zeneca, Bausch Health, Boehringer Ingelheim, Elpen, MSD, Mylan, Novo Nor-disk, Sanofi, and Servier. D.P.M. has given presentations and attended conferences sponsored by Amgen, AstraZeneca, and Libytec.
